online pattern designer | tester welcome

[f3y]

seems a strange way setting patterns with the sp-404(sx). therefore i needed some help - at least setting drums (spc. hihat) - thats why i made a small online program work with common browsers except ie. if someone like to test following pattern designer http://patnset.f3y.de/

should be very simple , set volume, sample, position and then choose pattern-bank-name and store file on SD card in folder /ROLAND/PATN/ o.e.
use displayed file-name to save data.

I'd like to but I don't understand the german stuff
